How to call a constructor in main

[ymbulk]

Hey guys, I am trying to call a constructor from PrepaidCard class in my main method, but I am not sure how to proceed.

As seen below, both the PrepaidCard constructor and the setCardID method have the ability to set the card ID.

public class PrepaidCard
{
        public PrepaidCard(String id, int token)
	{
		cardID = id;
		tokenBalance = token;
	}
        public void setCardID(String id, int token)
	{
		cardID = id;
		tokenBalance = token;
	}
}

Now in this block of code, I can successfully pass the id and token value by calling the setCardID method from the PrepaidCard class.
Now I would like to call the PrepaidCard constructor from the PrepaidCard class to pass the id and token value, instead of using the setCardID method.

public class PrepaidCardTest
{
	public static void main(String[] args)
	{
		PrepaidCard card2 = new PrepaidCard(id, token);
                
                System.out.print("Enter Card2 cardID: ");
		id = input.nextLine();
		card2.setCardID(id, token);
        }
}

Does anyone know how to call the PrepaidCard constructor from the PrepaidCard class, to successfully pass the id and token value, in my main method?
Specifically how to modify or replace this line of code so that it can correctly call the PrepaidCard constructor?

card2.setCardID(id, token);

You don't call the constructor, the JVM does that for you when you use the new keyword to create the object.

So get the ID and token first, then construct the PrepaidCard object in the way you're already doing now.

Thanks for your reply and reminder of cross posting.
I have omitted the declaration of the variables, but if you want, I can update the code to make it compile.
Do you know how to call the PrepaidCard constructor from the PrepaidCard class? So that I won't have to call the setCardID method, or is it not possible to call a constructor like that?
I would like to replace the setCardID method with the PrepaidClass constructor to pass the id and token, or is it not possible to do that and I have to use the setCardID method? Because in my assignment, it only supplies the PrepaidCard constructor and not the setCardID method.
Both of these (PrepaidCard constructor and setCardID method) are in the PrepaidCard class. If I can successfully pass the id and token to the PrepaidCard constructor, then I can delete the setCardID method as it is of no use.

You just copy pasted what you replied in your cross-post! That's just sad.
